We use water at home for a variety of reasons like cooking, gardening, showering, etc. If our homes are without clean water, we would not be able to perform our everyday functions. As a result, it is important for drinking water plants to consistently monitor the quality of water being sent to residences.
Drinking 6-8 cups of water a day is recommended to live a healthy lifestyle
Depending on the city, drinking water plants have different methods and instrumentation to clean influent. In the Region of Peel, we get our drinking water from Lake Ontario in addition to regionally and privately-owned wells. Here are some basic steps involved in drinking water treatment:
The first stage of treatment is called preliminary treatment. Screens are installed to remove large contaminants like bags or cloths before chemical treatment. Afterwards, chemicals are added to help particles stick together. This creates heavy flocs, making it easier to sink to the bottom of the tank to be collected.
Filters made of activated carbon purify the water by adsorbing to harmful contaminants like heavy metals. Chlorine and fluoride are also added during this process to disinfect the water and maintain oral health, respectively. Sulphur dioxide is then added to remove excess chlorine. The last step of this treatment process is to add ammonia to stabilize the chlorine as it travels through pumps and finally to residential homes.
Activated carbon has high surface area: volume ratios; ideal for adsorption purposes
The clean effluent is continuously monitored and tested to ensure it meets drinking water standards. The processes, equipment, and workers operate under stringent regulations and standards to make sure this water is clean enough to drink.
North America is fortunate to have clean water technologies as well as access to clean water. Unfortunately, 1 in 10 people in the world lack access to safe drinking water. This is being fixed through innovations in drinking water technologies that can clean water directly from a water source, majority through ultrafiltration. As our drinking water technologies advance, then hopefully more developing countries will have access to it.
